A bar graph titled, Puppets made by each puppeteer, plots Number of puppets, versus Puppeteer, for 4 puppeteers; Alex, Kalin, Bruce, and Marco. Bar heights are approximately as follows: Alex, 1; Kalin, 4; Bruce, 3; Marco, unknown. If the mean of the data set is puppets, find the number of puppets Marco made. puppets

Step-by-step explanation: To find the number of puppets Marco made, we first need to calculate the mean (average) number of puppets made by all puppeteers. The mean can be found by summing up all the numbers of puppets made by each puppeteer and then dividing by the total number of puppeteers.

Given data:

Alex made 1 puppet

Kalin made 4 puppets

Bruce made 3 puppets

Let the number of puppets made by Marco be .

Mean = (Total number of puppets made) / (Number of puppeteers)

Mean = (1 + 4 + 3 + x) / 4

Mean = (8 + x) / 4

Since the mean is equal to the number of puppets, we have:

Solving for x:

Therefore, Marco made 8 puppets.
